Patent number: 9146495Abstract: In a developer supply device, a developer carrying portion has a roller main body and a brush layer having flexible fibrous members. A casing includes a developer reservoir portion therein and is formed with an opening portion. The casing rotatably supports the developer carrying portion while the brush layer is exposed externally at the opening portion and opposes a supply target. A developer regulation portion regulates an amount of developer on the brush layer. The developer regulation portion includes a main part and a regulation part. The main part is fixed to the casing, has a plate portion, and extends from one end to another end in an extending direction. The regulation part is connected to the other end. The regulation part enters into the brush layer toward a central rotational axis. A prescribed rotational direction at the regulation part is substantially opposite to the extending direction.Type: GrantFiled: June 26, 2014Date of Patent: September 29, 2015Assignee: Brother Kogyo Kabushiki KaishaInventor: Keisuke Takahashi

Patent number: 8583016Abstract: A developing device includes a developer bearing body provided so as to face a latent image bearing body. The developer bearing body rotates to supply a developer to the latent image bearing body. A developer supplying member is provided so as to contact the developer bearing body. The developer supplying member rotates to supply a developer to the developer bearing body. A developer recovery member is provided so as to contact a surface of the developer bearing body that moves from a position facing the latent image bearing body to a position in contact with the developer supplying member by a rotation of the developer bearing body. The developer recovery member rotates to recover the developer from the developer bearing body. The developer recovery member is constituted by a brush roller.Type: GrantFiled: January 28, 2011Date of Patent: November 12, 2013Assignee: Oki Data CorporationInventor: Takuya Goto

Patent number: 5646719Abstract: A method and apparatus for cleaning residual particles from a surface that includes a cleaning brush with a fiberless segment and a fiber segment. These two segments enable the cleaning brush to both clean the surface with the fiber segment by rotating the cleaning brush and prevent cleaning when the fiberless segment is stopped, during development, in the home position. The fiberless segment, in the home position, enables image on image development, without retraction of the cleaner brush, by positioning the fiberless segment of the brush directly opposite to the surface where the image has being developed by image on image.Type: GrantFiled: October 10, 1995Date of Patent: July 8, 1997Assignee: Xerox CorporationInventor: Timothy J.
